Fence

ABSTRACT

A fence includes a plurality of fence units, which consist of plural vertical rods and plural lateral rods crossingly combined with each other. A decorative strip is combined with the uppermost one of the lateral rods, by means of plural grooves of the uppermost lateral rod and hooks of the decorative strip hooking in the grooves. The two ends of the uppermost lateral rod insert in an insert hole of a side post or a connect post and screwed tightly. Then the decorative strip is combined with the uppermost lateral rod as if covered on top of the rod. So the insert holes on the upper and the lower portion of the side post or the connect post are of the same shape and size, convenient for assembling and manufacturing.

BACKGOUND OF THE INVENTION

1. Field of the Invention

This invention relates to a fence, particularly to one constituted byconnecting a plurality fence units that include a decorative stripcombined with an upper lateral rod in a hooking way, and a side post ora connecting post provided with an insert hole for the uppermost lateralrod to fit therein for easy and quick assembling, without need ofmatching with the shape of the decorative strip, enabling the insertholes of the side post and the connect post being the same shape andsize for convenience of assembling and manufacturing.

2. Description of the Prior Art

Conventional metal (such as aluminum) fences are constituted byconnecting a plurality of fence units in series. Each fence unitconsists of plural vertical rods and plural lateral rods, with a connectpost provided between two fence units and a side post added so as tomake a complete fence by connecting them in series. The vertical andlateral rods are shaped mainly square, and a curved decorative strip isadded on the uppermost lateral rods for the whole neatness and thebetter perceptive feeling of a fence. However, the conventional fencehas the following disadvantages for makers.

1. The decorative strip is made integral with the upper lateral rod,having a different shape and size from the other lower lateral rods,needing an extra mold for manufacturing the upper lateral rod with thedecorative strip.

2. The upper lateral rod with the decorative strip has a different shapeand size from the other lateral rods, so the side post and the connectpost should have an upper insert hole of a different shape and size fromthat of a lower insert hole, causing inconvenience and complication inmanufacturing.

SUMMARY OF THE INVENTION

One purpose of the invention is to offer a fence constituted of pluralfence units connected with a side post or a connect post in series, andthe side post or the connect post is provided with plural insert holesfor the two ends of the uppermost lateral rod to fit in and then screwedtightly together. Every insert hole of the side posts or the connectposts are of the same shape and size for convenience of assembling andmanufacturing.

Another purpose of the invention is offer a fence provided with adecorative strip and an uppermost lateral rod combined with each otherby hooking, so its assembling is very easy,

The feature of the invention is the uppermost lateral rod provided withan upper surface having two grooves formed spaced apart thereon and withthe decorative strip having two hooks formed in two ends of two benthorizontal portions and spaced apart to correspond to the two grooves ofthe uppermost lateral rod, so the decorative strip may be combined withthe upper end of the uppermost lateral rod by simple hooking of the twohooks with the two grooves. In addition, the insert holes of the sidepost and the connect post are formed of the same shape and size for thetwo ends of the uppermost lateral rod to fit in, very convenient forassembling and manufacturing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A first embodiment of a fence in the present invention, as shown inFIGS. 1 and 2, is constructed with a plurality of fence units 1connected in series, and the fence unit 1 includes plural vertical rods10 and plural lateral rods 20 fixed with the vertical rods 10 in acrossing way, a decorative strip 30, and a side posts 40 and a connectposts 50.

The uppermost one 21 of the lateral rods 20, as shown in FIGS. 2, 3 and4, has two grooves 210 spaced apart on an upper surface and having amouth facing inward horizontally each other.

The decorative strip 30 has a curved upper horizontal wall and two benthooks 31 formed in two ends of two lower horizontal sections bent fromthe two ends of the curved upper horizontal wall and spaced apart tocorrespond to the two grooves 210 of the uppermost lateral rod 21 tocombine the decorative strip 30 with the uppermost lateral rod 21 as ifcovered on the uppermost lateral rod 21 as shown in FIG. 4. In addition,in order to let the hooks 31 to hook easily with the grooves 210, asshown in FIG. 3, the upper wall of the mouth of the groove 210 has atapered surface 211, and the hooks 31 also have a tapered edge 310 tocorrespond to the tapered upper surface 211.

Next, when the fence unit 1 is to be combined with the side post 40,firstly the uppermost lateral rod 21 of the fence unit 1 has two ends tobe fitted in the insert holes 41 of the side post 40 as shown in FIG. 5,and screwed tight. Then the decorative strip 30 is combined with theuppermost lateral rod 21, finishing assembling the fence unit 1 with theside post 40.

As the lateral rods 20 have only its uppermost lateral rod 21 insertedin the insert holes 41 of the side post 40, and the decorative strip 30is combined with the uppermost lateral rod 21 by means of hookingwithout inserting in the side post 40, and then the uppermost lateralrod 21 is screwed tight with the side post 40. Therefore, the insertholes 41 at the upper and the lower end of the side post 40 can be madeall the same size and shape, very convenient to handle or process.

Next, as shown in FIG. 6, when the fence unit 1 is to be combined withthe connect post 50, the uppermost lateral rod 21 is also combined withthe connect post 50 with the two ends fitting in the insert holes 51 ofthe connect post 50, so the connect post 50 has its insert holes 51possible to have the same shape and size, also convenient to handle andprocess. In case the fence unit 1 is to be combined with the connectpost 50 in a right angle, as shown in FIG. 7, the two ends of theuppermost lateral rod 21 only fit in the insert holes 51 of the connectpost 50, convenient to handle as well.

Next, a second embodiment of a fence unit 1 is shown in FIGS. 8 and 9,has a difference from the first embodiment in the uppermost post 21,having the grooves 210 provided with its mouth facing outward instead ofinward, and the decorative strip 30 has the hooks 31 shaped straight tohook easily in the grooves 210. And as shown in FIG. 8, the grooves 210have a tapered surface 211 and the hooks 31 have a tapered surface 311to correspond to the tapered surface 211 for the hooks 31 and thegrooves 210 easily hooking with each other. Although the grooves 210 areprojecting upward on the upper surface of the uppermost lateral rod 21,the height of the uppermost lateral rod 21 from the lower end to theupper edge of the groove 210 is the same as the height of the inserthole 41 of the side post 40 in the first embodiment, so it is notnecessary to alter the size of the insert hole 41.

In general, the decorative strip 30 is combined with the uppermostlateral rod 21 by means of hooking, unnecessary to fit in the insertholes 41 or 51 of the side post 40 or the connect post 50 or 60, so allthe insert holes 41, 51 and 61 can be the same shape and size, veryconvenient to assemble and manufacture.

While the preferred embodiments of the inventin have been described andit will be recognized and understood that various modifications may bemade therein and the appended claims are intended to cover all suchmodifications that may fall within the spirit and scope of theinvention.
